Spectrum Normalization Method in Vibro-Acoustical Diagnostic Measurements of Hydroturbine Cavitation
(The American Society of Mechanical Engineers (ASME), 1996)Full-scale vibro-acoustical diagnostic measurements of cavitation in four Francis 6 MW double runner turbines were performed. Two types of sensors were used—a hydrophone sensing waterborne noise ... -
Obstruction of Pipelines During the Flow of Waxy Crude Oils
(The American Society of Mechanical Engineers (ASME), 1996)When a liquid solution is cooled as it flows laminarly through a tube, a radial concentration gradient is established, which causes mass transfer of the solute to occur toward the tube wall. ... -
Interaction Between Sprays From Multiple Coaxial Airblast Atomizers
(The American Society of Mechanical Engineers (ASME), 1996)Phase Doppler measurements of size, velocity, liquid flux, and average mass fractions were obtained in sprays produced by three identical coaxial airblast atomizers, with their axes placed in a ... -
Transient Gas-Liquid Flow in Upward Sloping Pipes, Approaching the Wavy-to-Slug Flow Transition
(The American Society of Mechanical Engineers (ASME), 1996)A model is presented for transient, cocurrent gas-liquid pipe flow in the stratified-smooth and stratified-wavy flow regimes. It is based on the equations of continuity and motion in the direction ... -
Experimental Measurements in a Centrifugal Pump Impeller
(The American Society of Mechanical Engineers (ASME), 1996)Measurements of the 3-d velocities, total and static pressures have been made in a 0.89 m diameter commercial pump impeller, using air as the working fluid. Results at the peak efficiency ... -
Computation of Three-Dimensional Viscous Flow in High Reynolds Number Pump Guide Vane
(The American Society of Mechanical Engineers (ASME), 1996)A three-dimensional Navier-Stokes solver which utilizes a pressure based method is used to compute the incompressible flow field through the inlet guide vane (IGV) of a high Reynolds number ... -
Air Influence on Similarity of Hydraulic Transients and Vibrations
(The American Society of Mechanical Engineers (ASME), 1996)The effects of wave speed variation due to air content on the validity of similarity laws for model studies of hydraulic transients and hydraulic vibrations were investigated. Studies show that ... -
